A Dynamic and Distributed Scheduling for Data Aggregation in Ubiquitous Sensor Networks Using Power Control

Abstract

Data aggregation scheduling in ubiquitous sensor networks is a major research interest for many researchers. Very little research is carried out to schedule the nodes in ubiquitous sensor networks for maximizing the throughput and utilize the hardware resources effectively. The traditional graph model does not model the interferences occurring from the concurrent transmissions in the Ubiquitous Sensor Networks. Hence in this paper we propose a new network model for the USN called a power control collision interference free model and a novel distributed data aggregation scheduling protocol which is adaptive to the rate and power. We tested the protocol in a USN consisting of 50, 100, 150, 200, and 250 number of nodes with different topologies and varying degree 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, . . ., 40. We compared our results with the other protocols and proved that our proposed power control collision interference free model yields better results.

Distributed Broadcast with Minimum Latency in Asynchronous Wireless Sensor Networks under SINR-Based Interference

“…In recent years, physical algorithm, that is, algorithm for the physical interference model, has attracted a lot of attention both in the algorithm community and in the communication community. Much efforts have been paid in developing efficient physical algorithms for a wide range of topics in wireless network, including capacity [24], link scheduling [25], data collection, and aggregation [26][27][28], topology control [29], and so on. For recent results and references we refer the readers to the survey [30].…”
